vI PERPETUAL CALENDAR.

To all whomct may concern.' y., y y Be it known: that I, GEORGE vW'. BAILEY,

a citizen of the Unitedl States, residing at Arlington, in the county ofAleXandria and State of Virginia, have invented certain new and useful Improvements in Perpetual Cal.- endars, of whichthe following `is a specification, reference being had tothe accompanying drawings.`

This invention relates to calendars of that type generally designated as perpetual,

y i finents of the parts that I shall hereinafter 3 is a rear elevation thereof; Fig. 4E is a de4 tail perspective view of one of the numeralk bars; Fig. 5 is a `fragmentary perspective and has for its primary object to produce a calendar of this character whereby the month indicating numerals may be easily and quickly transposed ror changed and.

properly located with respect to the week days.

`The invention has for a further object t0 produce a perpetual calendar having interchangeable bars provided withnumerals whereby a complete monthly calendarffor thirty-one, thirty, ytwenty-nine or twentyeight days may be easily and quiclily'produced and the numeralsproperly arranged with relation to the week day characters.

"The invention has for another object to provide a calendar of the above character which is extremely simple in its construction,

very serviceable in practical,` use `and capable -of manufacture at comparatively small cost.

With the above and other objects in viewas will become apparent as the description proceeds, the invention consists in certain constructions, combinations `and arrangefully describe and claim. y

VFor a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in whicht Figure 1 is a front perspective view of a calendar constructed in accordance with the preferred embodiment of my invention;r

Fig. 2 is a' vertical sectiojnthereof; Fig.

view looking at the rear side of the base. Fig. G is a fragmentary view ofone ofthe date-carrying bars. Fig. 7 is a" detail perspective view of a month indicating block.

In the accompanying drawings wherein I have illustrated myI invention in its prevSpecification ofvLetters `Patent.

ferred form, 'a basel or frame is provided consisting of the'upper and lower parallel horizontal bars indicated at 5 and 6 re vspectively.` These bars are connected at their. ends bythe parallelvertical bars or cleats 7, said cleats projecting beyond the rear faces. of Usaid horizontalbars.

or otherwise delineated. y y

To the vrear face of the upper horizontal ,body bar', ka pluralityl of wire loops or staplesI 10 arel secured and a series of pins 11 corresponding in number to the staples 10 are fixed in the lower horizontal bar 6 and projectrearwardly therefrom. A plurality of `date bars 12 corresponding in number to the Adays of the week, areprovided upon ,their upper ends with pins or studs 13 which are adapted to be engaged y Patented sept; e, i914.. Application filed April 29, 1914. Serial No, 835,203. i

n p The upperbar 5 is provided upon its'lower edger witha forwardly inclinedor beveled rib or,` projection yS upon which theweekday indicating letters yas shown at 9 are printed inA the'respectivestaples 10. Each of the bars 12 is provided with spaced openings 15 7inits lowerend, `with theexception of' the barbearing the numeral 1, which has only one opening 15 formed therein. These openings are adapted to engage the pins 1l projecting from the rear face of the lower base bar 6.` Four of the bars l2 are provided-with numerals indicated at .V1/.it upon onefface.; The other" three bars have nu-v merals ltron both faces, `therebein'g four. numerals on one face, andfive on the other.`

By proper yarrangement of these three bars with the others, as hereafter set forth, aI

calendar for. any month,virrespective of the number of days, may be obtained.

' l In Fig. 1 of the drawings,\I have shown the :bars 12 properly arranged upony the base of the calendar for amonthv of thirtyf one days, in which arrangement, it will be noted that all three of the numeral bars have .their faces whereon the five numerals 111 are provided visually disposed: If, however, the month contains `only thirty days,

oneof the bars is reversed yso as to Iexpose whereinA the month has twenty-ninedays,

that side to view which contains the four numerals, 3, 10, 17 and 24. For the monthof t February, occurring in a leap year,r-

two ofthe bars are reversed, only that hav-`L .ing the five numerals commencing with 1,

being exposed. For theimonth of-February,-

not occurring in a leap year, all of the three bars are reversed pso as to show a month having twenty-eight days.

It will be understood that in assembling the date bars u aon the base or frame of the calendar, the 1bar having the numeral 1 thereon is first arranged in line with the proper week day letter 9, and the other bars then disposed in proper sequence, the studs 13 on the bars being engaged with the respective staples 10 and the openings in the lower ends of said bars receiving the pins 11. If the first of the month falls on Saturday, the bar bearing numeral 1 is properly placed, and other the upper openings 15 in the date bars are enoaged with the pins 11. When the vfirst o-f the month falls on any other day, those date bars which are arranged on theright of the bar containing the numeral 1, (looking from the front) have their lower openings 15 engaged with the pins 11 while those bars on the left thereof have the upper openings engaged with said pins.

To one of the cleats or bars 7 of the calendar base, one end of an elastic strap 16 is secured, the other end of said strap being provided with a suitable hook 17 for engagement with the keeper 18 on the opposite vertical bar 7. It will be understood that this elastic strap is provided for the purpose of holding the bars 12 in position and preventing their accidental displacement. The upper edge of the lower base bar 6 provides a ledge 19 for pencils, pens etc. `It will be found of convenience when the device is used as a desk calendar. To the rear face of the upper base bar 5, the ends of a chain indicated at 20 may be attached whereby the calendar may be suspended upon a wall.

The upper base bar 5 is provided in its front `face with an elongated horizontally extending recess to receive a month block 21. It will be understood that three of these blocks are provided, each having one of the months printed upon each face thereof. When the date bars 12 are changed, the month block is of course removed from the recess in the base bar and the block indicating the next ensuing month placed therein. The front face of the base bar 5 is also provided with an additional recess to receive a block 22 containing two numerals indicating the year, the first two numerals of the year being printed upon the face of said bar. It will be understood that in order to change the year, the block 22 is simply removed and another block placed therein. Each of the bars 12 is also provided with a series of wire -loops or staples 23 projecting laterally therefrom opposite the several nu- Amerals on the bar. These staples are adapted to receive hooks formed upon the members 24. These members have printed or otherwise indicated upon one ofv their faces, the different phases of the moon.

From the foregoing description taken in connection with the accompanying drawing, it is believed that the construction, manner of use and several advantages of my invention will be clearly and fully understood.

- It will be apparent that by the provision of the transposable date bars, the months may be easily and quickly changed and said bars properly arranged with respect to the week `day letters to disclose a month of any number of days.

e Thedevice provides a calendar which is neat and attractive in appearance, and of great convenience in practical use.

Owing to the eXtreme simplicity of my invention, it will be appreciated that the same can be produced at comparatively` small manufacturing cost.

Vhile `I have shown and described the preferred construction and arrangement of the several elements employed, it will be understood that the device is susceptible of many minor modifications therein and I therefore reserve the privilege of resorting to all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

y Having thus described the invention, what is claimed is:

1. A perpetual calendar including a base provided with weekday indicating characters, numeral carrying bars corresponding in number to said characters, pins fixed in the base, each of said bars being provided with an opening in one end to receive one of said pins whereby the bars may be transposably arranged upon the base to indicate any month in a year, and means for retaining the numeral carrying bars upon the respective pins.

2. A perpetual `calendar including a base provided with week day indicating characters,l numeral carrying bars corresponding in number to said characters, a plurality of pins fixed in said base, a plurality of staples secured upon the base, said numeral carrying bars having openings in one of their ends to receive the respective pins and provided with studs upon their other ends for engagement in the respective staples whereby said bars may be transposably arranged upon the base toindicate any month in'a year, and means for retaining said bars in position upon the base.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
